Hi @jieljiel 

The FIR extension is the best way to detect the common block but the current approach also works. I was wondering that we can use this PR for now as it fills a missing hole in the debug support. When the extension in FIR to detect common block is available in future, we can use that and remove the DAG walking. If @jeanPerier thinks this is OK then I can rebase/update the PR and address any other comments.
